    [CLOSED] Error Message is not shown

    Hi,

    With the following code snippet, when entering a value not qualified for MinValue, the validation is executed, border turns red but the error message is not shown

                               <ext:CompositeField ID="cf2" runat="server" FieldLabel="Composite" LabelWidth="140">
                              <Items>
                                 <ext:DisplayField ID="df3" runat="server" Width="50" Text="Min">
                                 </ext:DisplayField>
                                 <ext:NumberField runat="server" Width="100" MinValue="5" HideLabel="true" FieldLabel="Min"
                                    ID="minAdvPurchase" AllowDecimals="false" AllowNegative="false">
                                 </ext:NumberField>
                                 <ext:DisplayField ID="df4" runat="server" Width="50" StyleSpec="text-align:right;"
                                    Text="Max">
                                 </ext:DisplayField>
                                 <ext:NumberField runat="server" Width="100" MinValue="5" FieldLabel="Max" ID="maxAdvPurchase"
                                    AllowDecimals="false" AllowNegative="false">
                                 </ext:NumberField>
                              </Items>
                           </ext:CompositeField>

    Hi,

    Please set CombineErrors="false" for the CompositeField.

    But it causes another issue when doing a validation of the FormPanel ( containing the CompositeField ). It does not show error messages.

    Well, there is no such option to have field's and combined messages at the moment.

    But I can suggest a way to have both messages. But I'm not sure it will work in all cases, but it should.

    Please see the example.

    The key points are:

    1. CombineErrors="false" for the CompositeField;
    2. The BeforeRender listener of the CompositeFIeld.

    Example

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

    <title>Ext.Net Example</title>

    <script type="text/javascript">
        var onBeforeRender = function (cf) {
            cf.onRender = cf.onRender.createSequence(function () {
                this.eachItem(function (field) {
                    field.markInvalid  = field.markInvalid.createSequence(this.onFieldMarkInvalid.createDelegate(this, [field], 0));
                    field.clearInvalid = field.clearInvalid.createSequence(this.onFieldClearInvalid.createDelegate(this, [field], 0));
                });
            });
        };
    </script>

    Hi,

    Thank you. My application has a lot of composite fields.

    And do you want to apply this change for all CompositeFields globally avoiding setting up BeforeRender for each one?
